Abstract
The utility model relates to a full-plastic high accuracy electronic centigrade meter. The utility model comprises mainly a meter shell, a front cover, a rear cover, a decorating ring, a main grid seat, a guide seat, a dust removing end cover, etc. which are molded by engineering plastics, and besides, the utility model adopts a high precision and phase demodulating capacitance grate sensor and achieves basically the low cost and micrometer stage precision of full plasticization.
Description
The utility model relates to a kind of electronic measuring instrument, especially overall plastic high-precision electronic dial gauge.
At present, the manufactured materials of known mechanical dial gauge and electronics dial gauge mainly is a metal material, and precision all is 0.01mm.This makes the manufacturing cost of dial gauge higher, under the situation that modern digital display technology is popularized day by day, is unfavorable for applying of electronic digital centigrade indicator.
The purpose of this utility model provides a kind of overall plastic electronics dial gauge of low-cost and high-precision.
The purpose of this utility model is achieved in that and must adopts the metal material except that attachment screw, pin, extension spring, sounding rod, measuring head reach the axle sleeve that is slidingly matched with sliding gauge rod, watchcase, protecgulum, panel, case ring, main grid seat, guide holder, bonnet, display case, dustproof end cap etc. all adopt engineering plastics (enhancement mode) injection molded, and adopting high-precision phase demodulating sensor, the low cost that reaches overall plasticization substantially requires and high-precision purpose.
Owing to adopt such scheme, the manufacturing cost of electronics dial gauge is reduced more than 30%, precision then reaches micron order, and resolution is 0.001mm, and the measuring accuracy and the error of indication are higher than the percentage surface and are lower than clock gauge.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structure of the present utility model and main moulding cut-away view.
Among the figure, 1. measuring head; 2. sounding rod; 3. axle sleeve; 4. watchcase (injection moulding); 5. bonnet (injection moulding); 6. pin; 7. main grid seat (injection moulding); 8. sensor main grid; 9. shaddock cover; 10. dustproof end cap (injection moulding); 11. case ring (injection moulding); 12. display; 13. display case (injection moulding); 14. guide finger; 15. guide holder (injection moulding); 16. protecgulum (injection moulding); 17. the secondary grid of sensor; 18. extension spring; 19. membrane buttons panel; 20. screw.
In the embodiment shown in fig. 1, the main big part part watchcase (4) of dial gauge adopts injection mo(u)lding, both can on material, reduce cost, can save the machining expense again, be a major event of dial gauge energy-conservation of consumption reduction, all in the watchcase (4) are installed fit dimension and screw single injection-molded, and axle sleeve (3 and 9) is pre-buried fixing when injection moulding, be to guarantee the concentricity of axle sleeve (3) and axle sleeve (9), should pack into earlier in the endoporus of axle sleeve (3 and 9) before the injection moulding one cooperates mandrel preferably.Axle sleeve (3 and 9) is moulded should a flat position in the tight position, rotate in case axle sleeve (3 and 9) is moulded tight back.Moulding protecgulum (16), bonnet (5) are connected with watchcase (4) with self-tapping screw.Case ring (11) is connected with protecgulum (16).Guide holder (15) is screwed in the last in-plane of watchcase (4) and cooperates slip with guide finger (14).Display case (13) is connected with self-tapping screw with the circuit board of the secondary grid of sensor (17), the secondary grid of sensor (17) are fixed in watchcase (4) with self-tapping screw and go up the plane, sensor main grid (8) is adhered on the moulding main grid seat (7), and main grid seat (7) is fastened on the sounding rod (2) with screw.Measuring head (1), dustproof end cap (10) are connected to the two ends of sounding rod (2), and membrane buttons panel (19) is bonded in protecgulum (16) front.
The utility model also is applicable to overall plastic electronics clock gauge.
Claims (2)
1, a kind of overall plastic high-precision electronic dial gauge, the secondary grid of high precision phase demodulating sensor are fixed in watchcase, the sensor main grid is bonded on the main grid seat, the main grid seat is fastened on the sounding rod, it is characterized in that: parts such as watchcase, protecgulum, bonnet, case ring, main grid seat, guide holder, dustproof end cap all adopt the engineering plastics single injection-molded.
2, overall plastic high-precision electronic dial gauge according to claim 1 is characterized in that axle sleeve pre-buried being fixed in the watchcase when injection moulding, and axle sleeve is pre-buried moulds tight position a flat position.
